You're a human while the Star sanses are vampires and also your boyfriends. You let them fed on you since you don't mind.
You're in the kitchen making dinner when you felt someone bite the back of your neck playfully, you knew this was Ink since he was playful with his bites. After he finished feeding Dream dragged him away to the living room as you continue cooking and Blue is reading a book on the couch.
Dream: "Ink you gotta stop surprising them like that and give a warning."
Ink: "Nah~"
Dream sighs
Dream: "If you kept catching them by surprise you might hurt them."
Ink: "Oh please! They know I won't actually hurt them, right Blue?"
Blue: "Don't know why you brought me into this but Ink's right, we're lucky they let us fed off of them but Dream is also right, we don't want to hurt our Y/N."
